Abstract

Dentoalveolar ankyloses of primary tooth sometimes cause impaction of its successor tooth. In this condition, extraction of the ankylosed primary tooth and orthodontic forced eruption of the impacted permanent tooth may be a choice of treatment. In this case report, we present a 23-year-old female with Angle Class II malocclusion, whose mandibular left 2nd premolar impacted due to ankyloses of its primary tooth. She also had dental arch crowding and gummy smile problems. The patient received full-mouth orthodontic non-extraction treatment combine using TADs. As a result, her problems of malocclusion and gummy smile improved.
